All Pentium M Models

Banias

The first Pentium M models were based on a core called Banias, which had a 32 KB L1 instruction cache, a 32 KB L1 data cache, a 1 MB L2 cache, worked externally at 400 MHz (100 MHz transferring four data per clock cycle), had SSE2 instructions support, Enhanced SpeedStep technology on models SL6NA and SL6P4 (which reduces the CPU clock in order to save battery life when the computer is idle), 130 nm manufacturing process, socket 478 or 479 pinout and 77 million transistors on a area of 3.26 squared inches (82.79 mm2), using copper on its metal layers.
